not cut through the rubber, consequently is pushed back a distance equalto the thickness of the sheet of rubber which is being measured. Theamount of this backward movement of the flat gage roll is in the mannerdescribed indicated in thousandths of an inch by the dial pointer; thuspractically instantly without stopping the calendering machine orinterfering with the running out of the rubber sheet the thickness ofthe sheet can be gaged to ascertain whether or not it is coming toothick or too thin. The disks, of course, eut through the rubber, but asthe rubber is soft and sticky and particularly if it is to beimmediately applied to a fabric, when it is passed between the rollswhich unite it to the fabric the slits which the disks cut are closedtogether. In measuring the thickness of the sheet as it comes from thecalender rolls, or in ascertaining whether the sheet is varying from thedesired thickness, the instrument can be held by the hands and thrustradially toward the axis of the calender roll on which the sheet isrunning, or it may be rested upon a bar or bracket and thus thrustagainst the calender roll.

In the second form of instrument illustrated, instead of having twocutting disks and one gaging roll, as in the above described form, thereis one cutting disk, which is immovable with relation to the handle, andtwo fiat rolls, which are held by a slide movable on the handle and aremoved backward according to the thickness of the sheet being measured.In this form the cutting disk 15 is mounted in the forked end of a frame16 which is desirably tubular. On this frame is an ear 17 bearing a stopscrew 18 with a lock nut 19. The dial gage 2O is fastened to this frame.Moving on the outside of this frame is a tubular slide 2l carrying a pin22 which projects upwardly through a slot in the frame between the stopscrew and the stem of the dial gage. On the forked front end of thisslide are the gage rolls with flat surfaces 23. A spring 24 with one endfastened to a pin 25 in the frame and the other end fastened to a pin 26in the slide draws the slide forward and holds the pin against the endof the stop screw. When this structure is used the cutting diskpenetrates the material and the broad Hat surfaces of the gage rollsforce the slide back and through the pin carried by the slide cause thedial to indicate the amount of backward movement of the rolls, andconsequently the thickness of the sheet being measured.

In the form shown in Fig. 7 the rolls are arranged in a vertical plane.In this form one roll 27 is mounted on the forked end of the slide 28,which has a pin 29, and the other rolls 30 are mounted on forks at theends of the frame 31. This frame is provided with astop screw 32 whichbears against the opposite side of the pin carried by the slide, fromthe point where the stem 33 of the indicating dial bears.

Instruments embodying this invention, besides being used for gaging asheet of rubber on a calender roll, may be employed during the gaging ofa calender roll which is in the process of being ground, so that a truesheet will be produced. When these rolls are being formed it iscustomary to grind them with a slight crown which will when rolling theparticular stock in question just counteract the spring of the rollsunder the work of rolling a sheet, and thus produce a sheet of uniformthickness from end to end of the rolls. lVith an instrument of thisnature a sheet can be very easily and quickly gaged at each particularpoint on the rolls so as to detect any of the errors which might haveresulted from the grinding.

The invention claimed is:

1. A measuring instrument consisting of a frame, a disk with a sharpenededge mounted on the frame and having Vits axis stationary with relationthereto, a roll with a flat edge connected with the frame and having itsaxis movable with relation thereto, the axes of the disk and rollnormally being in alinement, and a gage carried by the frame andoperatively connected to indicate the amount of movement out ofalinement of the axis of the roll with relation to the axis of the disk.

2. A measuring instrument consisting of a frame, axles fixed to theframe, an axle movable along the frame, penetrating disks mounted uponsaid fixed axles, a surface roll mounted upon said movableaxle, and agage carried by the frame and operatively connected to indicate theamount of movement of the axle of the surface roll with relation to theaxles of the penetrating disks.

3. A measuring instrument consisting of a frame, a pair of rotarypenetrating disks with sharpened edges mounted upon the frame, a slidemovable along the frame, a flat faced roll rotarily mounted upon theslide, and a gage actuated by the movement of the slide to indicate theposition of the roll with relation to the disks.

4:. A measuring instrument consisting of a frame, a sharpened rotatorydisk mounted upon an axle fixed with relation to the frame, a broadedged roll mounted upon an axle movable along the frame, adjustablemeans for limiting the outward movement of said roll, and means forindicating the amount of inward movement of said roll with relation tosaid disk.

5. A measuring instrument consisting of a frame, rotatory means mountedupon the frame for penetrating the material to be measured, rotatorymeans yieldingly connected with the frame and designed to bear on thesurface of the material to be measured, and a gage actuated by themovement of said yielding means to indicate the position of said surfacemeans With relation to said penetrating means.

6. A measuring instrument comprising a handle, carrying sharpenedrotatory disks adapted to penetrate the material to be measured, arotatory roll With a broad pe riphery adapted to bear on the surface ofthe material to be measured, said roll being movable radially Withrelation to the disks, means adapted to adjust the relative positions ofthe disks and roll, and a gage actuated by the movements of the roll toindicate the amount of movement radially of theroll With relation tothe' disks.

7. A measuring instrument having tWo connected frames movable Withrelation to each other, a spring thrusting between and holding saidframes in normal relation, surface and penetrating rolls mounted on andcarried by the respective frames, a dial gage fixed to one frame, andmeans iXed to the other frame and engaging said gage so as to cause itto indicate the amount of relative movement of the frames from normalposition.

8.,A measuring instrument having a tubular frame, disks with sharpenedperipheries rotarily mounted on the frame, a dial gage mounted on theframe, a slide fitted Within and movable longitudinally With relation tothe frame, a roll With a broad periphery rotarily mounted on and movableWith the slide, and means projecting from the slide and engaging saidgage for indicating the movement of the slide and roll With relation tothe disks.

9. A measuring instrument comprising a frame, rotatory means having afixed position on the frame and designed to penetrate the material to bemeasured, means designed to bear upon the surface of the material to bemeasured, means whereby said surface bearing means is movable withrelation to the frame,and a gage connected and arranged to be actuatedby and to indicate the movements of said surface bearing means withrelation to the frame and the penetrating means carried thereby.
